At this time, the opening button 5 or the remote opening button SBS1 is released, and the opening relay coil RA is still energized, and the rectifier bridge BG is energized. The motor forward circuit is energized through the rectifier bridge BG to control the motor M to rotate forward, so that the load switch performs the opening operation. This is the process of the switch operation controller performing the opening action. When the switch position reaches the open position, that is, the switch position signal open position M2-2 is closed, the switch position signal closed position M2-3 is disconnected, the opening relay coil RA loses power, and the opening action is completed.

The motor M has a large power when starting, and the current limiting resistor RT uses a high-power resistor to limit the current of the circuit to prevent excessive current from damaging other components.
